I tried to install each package.
I download this package: compat-libcap1-1.10-1.src.rpm

rpm -i compat-libcap1-1.10-1.src.rpm

and I got this output:

When I was installing oracle 11g on CentOS there was a warning about some packages not installed. But I have ignored the warning and all things are fine. Oracle 11g can't recognise new packages so you can just ignore when the warning comes.
